Celebrate the good stuff while it's here. I think "Black and British" is terrific (BBC 2 on Wednesdays this week's was the third of four). David Olusoga is intelligent, engaging, very positive. There's a clever inclusiveness running through the series, whereby local people of all kinds are invited in, to share this common heritage, so that the aging, white members of a bowls club gather round to applaud the erection of a plaque on their clubhouse, recording the career of a former slave of whom none of us have ever heard - until now. The series is full of interesting stories, stunning characters, which makes you think "Why haven't we heard about this before?" But now we have, and the plaque, and the series, and the book are there, leaving a trail which others will pick up, and from which we'll all end up wiser.
